Re: [EnergyPlus_Support] about MTF

[Zheng Li <lizhenghdf@xxxxxxxxxxxx>]

Dear:
 
The file that I have uploded named "W only enve MTF" had only envelope, no infirltration and others. Then the latent load should be the permeating from building materials. that value is too large! Why?

Edward Lyon <eglyon@xxxxxxx> wrote:
The latent load that permeats building materials is small.  The latent
load that is carried by air penetrating the building envelope is large. 
If you have normal infiltration of say .35 air changes, the
recommendation for a small house, you may have significant latent load
depending on your climate.
